This Live Granular Processor lets you decompose audio into bits and pieces or lovely clouds. Dual Live Buffers Quantum Granulator is a powerful live granular processor designed for deep, hands-on sonic manipulation in real-time. Two independent recording buffers capture your signal and let you freeze, loop, or continuously record audio for instant transformation. Whether you’re sampling from the Main Input, Sidechain A, or Sidechain B, you’re in full control of what goes in — and what comes out. Musical Grain Engine Trigger grains freely in Hz or lock them to tempo for tight rhythmic effects. Adjust grain length, offset and density — from crisp stutters to blurred, cinematic clouds. Randomization adapts to your mode: in Hz it behaves like a geiger counter, adding sharp, bursty unpredictability; in BPM sync it becomes more spray-like, scattering grains around the beat for rhythmically coherent textures. Expressive Pitch Control Our easy-to-use scale picker lets you quantize grains to 30+ built-in musical scales, create your own, or let randomness take over. Play grains via MIDI to turn Quantum Granulator into an expressive granular instrument. Pitch shifting covers a broad ±24 semitone range and a separate fine control allows subtle adjustments within ±1 semitone, perfect for microtonal tuning or adding vibrato-like motion. Versatile Grain Shaping An intuitive 2D Envelope XY pad lets you sharpen or soften vertically, adjust attack and release horizontally. Control level, panning, and filtering to craft subtle movement or fully chaotic sound clusters. Shape the balance using the mix section — from subtle texture to complete granular obliteration. Granular Synthesis, Made Playable Quantum Granulator isn’t just a tool — it’s an instrument. Built for performers, producers, and sound explorers alike, it offers a deep but immediate interface into the world of granular synthesis, with every detail tuned for musicality and expression. Quantum Granulator is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).

AudioGrafik is a real-time audio visualizer and VJing space for iPhone and iPad. Turn music into moving images with 24 scenes, 20 effects and compositions that evolve with sound. Play a track, choose a visual world and let the music shape what happens next. SEE YOUR MUSIC MOVE Bass, percussion, melodies and changes in energy bring the image to life. An impact can shake a material, a musical phrase can guide a flowing shape, and a build can change the composition. This music visualiser gives your listening a visual presence, from quieter passages to more intense moments, with forms and movement that respond to the audio. EXPLORE 24 VISUAL SCENES Electric Filaments brings vibrations and percussive flashes into view. Spectral Prism refracts coloured beams by day or night. Photon Race follows glowing bikes through turns, boosts and collisions. Herbarium grows an ink-drawn 3D garden with twirling leaves. Discover fluids, architecture, Fibonacci and Bloom too. RESHAPE THE IMAGE WITH 20 EFFECTS Work with Glass, Curved Glass, Prisms, Caustics, Webs and Rose. Try the panel divisions of Comics, the relief of Emboss, the patterns of Weave and the transformations of Polarisation. Change an association to see a familiar scene differently: move between organic forms and graphic structures, explore colour and depth, or bring out another texture in the music. 8 WAYS TO COMPOSE YOUR VISUALS Choose Scenes, Effects and Mixers independently. Explore Overlay, Fusion, Territories, Inlay, Erosion, Relay, Black Key and Imprint. Black Key reveals a scene through another’s dark areas; Imprint retains traces of their relief. Territories spreads up to three scenes across the screen, holds their positions longer, then moves them on a musical event. Choose the allowed methods and let the music shape the composition. No more than three scenes coexist, including during transitions. CHOOSE YOUR AUDIO SOURCE Search for a track in the online catalogue, import an audio file from Files or enable the microphone to respond to ambient sound. Bring your own compositions into the audio visualizer and discover how their changing energy translates into motion. In microphone mode, the picture reacts to sound around your device without playing that microphone input through its speakers. KEEP YOUR LISTENING ORGANIZED Find your favourites, recently played tracks and playlists. Add tracks to the queue and prepare what comes next. Open the expanded player to rearrange upcoming songs by dragging them into a different order. Keep the listening session moving while you explore your chosen scenes and effects. MAKE ROOM FOR THE PICTURE Immersion lets the controls move out of the way so the visualizer can fill the screen. Tap the image to bring them back, adjust your choices and continue listening. The interface adapts to portrait and landscape on iPhone and iPad, with a control panel suited to larger windows. Move between music, visuals and settings as part of the same session. RECORD AND SHARE A VIDEO Record the visuals together with sound. Stop recording to open the standard iOS share sheet, then share the video or keep it in Photos or Files using the available actions. Compare several combinations on the same passage to find a look that fits your music, from geometric scenes to more organic motion. The catalogue requires an Internet connection. Microphone access needs your permission and stops when the app goes into the background. Files must be accessible on your device before they can be opened. All scenes and effects in this version are available without in-app purchases. No AudioGrafik account is needed to get started. The online catalogue is provided through the SoundCloud API. AudioGrafik is an independent app. GIVE EACH COMPOSITION TIME TO UNFOLD Off-centre scenes hold their positions before a new musical impulse moves them. Watch contours, leaves and beams develop in depth, then try another combination to explore a different visual atmosphere.
